WILLIAM C. -MCLAUGH]:IN, OF OAKLAND, CALIFORNIA, ASSIGNOR OF ONE-FOURTH TO FizEDERIcK E. wHTT-NEY,

No Drawing.-

To all who-m 1t may concern:

Be it known that I, \VILLIAAI G. M0- LAL'GIILIN, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented ne and useful Improvements in Explosives, of which the following is a specification.

My invention relates to an improved ex plosive which is" especially desirable for mining in confined spaces, and also for use in gunsand the like.

My ii'iventioi consists of the improved compound which I will hereinafterfully describe and claim.

In carrying out my invention I proceed substantially as follows: Sixteen ounces of chlorate of potash whichhas been thoroughly pulverized and one half an ounce of soot in a dry condition, are thoroughly mixed in any suitablemanner. Sixteen ounces of sugar and one drain of spirits of wine or alcohol are then stirred together until the sugar is all moistenedf Four ounces, dry weight. of rice, or equivalent cereal, are boiled in water to form an extract or paste which after straining is concentrated by boiling to two and one half ounces, after which the extract is mixed with the pievi'ously prepared sugar and spirit and is cooked, continually stirring until it will form a thread-like string after each drop when lifted and allowed to fall back. This is then takenfi'oni the fire, the stirring contiiiued'and the previously prepared chlbrate and soot added until it thickens or recrystallizes. \Vhcn suliiciently stiff and dry it is passed through a screen to complete the gra'i'uilation. 'lhe cereal has, as one e ect, to 'n'irtially granulate or separatethe mass which would otherwise become a hard compact cake, which could not be properly Specification of Letters Patent.

Application filed October 6, 1909. Serial No. 521,406.

ExPLosIvE.

Patented Aug. 23, 1910 l granulated, and it somewhat retards the violent explosive action of the chlorate. About one-half a drain of sulfur and onelialf a drain of aluminum are finally added and stirred or rubbed in, the aluminum giving the grains a bright or steel color. Soot from fats or grease is not desirable, but it should be absolutely dry and free from any greasy consistency.

' By actual test this powder has been found to be exceedingly useful for guns for sportbeing greatly educed, and the interior of the gun is very little fouled after much shooting. it is believed that the extract of fiuence inkeepiiig the interior of the gun clean. hen used for blastingand mining purposes in confined shafts and tunnels poisonous fumes or gases which will injure anything.

ing its strength; all that it is necessary to do is to dry it and recrush, or gianulate it by passing through a screen as before.

Having thus described my invention what I claim as new and desire to secure by Let ters Patent is:

An explosive compound. coii'iposed of wine, a cereal paste, sulfur, and aluminum in substantially the proportions specified.

ing and like purposes? the noise and recoil riceor other cereal has a considerable'inunder ground, it is found that there is no lowd er thus made can be wet without loschlorate of potash, soot, sugar, spirits of.
